Fender having element conforming to mounting bracket

ABSTRACT

A fender includes at least one element extending therefrom that is adapted to engage a mounting bracket affixed to the object to which the fender is to be attached, e.g., a trailer. The element is preferably a curved flange that extends outwardly from an inner bottom edge of the fender.

FIELD OF THE INVENTION

The present invention relates to fenders, and more particularly to a fender having an element, such as a flange, that conforms to a mounting bracket.

BACKGROUND OF THE INVENTION

Proper alignment is important when mounting a fender on a trailer. However, aligning a fender in a predetermined position can be difficult due to misregistration of the fender. In the past, those skilled in the art have found it difficult to properly align a fender without a significant amount of effort, therefore wasting time. Furthermore, alignment was often done visually, therefore, allowing for human error.

Due to the substantially horizontal top surface of a conventional fender people tend to step on trailer fenders while getting on and off the trailer. Stepping on the fender places a person's entire body weight on the fender, which can result in damage to the fender if it is not constructed of sufficiently strong materials and designed to withstand such forces. Also, repeatedly stepping on a fender can cause the connection points of the fender to fatigue, which can eventually result in failure at a connection point.

A long felt need exists for a fender that is strong enough to help prevent failure from repeated loading and unloading and that provides easy alignment and simplified mounting.

Description of the Preferred Embodiments

Conventional fender shapes and designs are well known in the art, and the fender shapes illustrated herein are to be considered exemplary and not limiting in any way. As illustrated herein, the fender is provided in combination with a trailer for towing objects, such as automobiles. However, neither the type of trailer nor the object which can be towed thereon is meant to be a limitation on the present invention. The fender can be used on trailers having any number of wheels or axles, for example, a TOW DOLLY^(SM), commercially available from U-Haul International, Inc., which has two wheels rotatably mounted on one axle, or an AUTO TRANSPORT^(SM), commercially available from U-Haul International, Inc., which has four wheels, two each rotatably mounted on each of two axles. The fender can be used on trailers provided for towing automobiles, trucks, boats, motorcycles, personal watercraft, heavy equipment, motor homes, etc. and on flatbed or enclosed general purpose utility trailers.

Referring to FIGS. 1-3, in a preferred embodiment, the fender 10 is adapted to be mounted on a mounting bracket 34. The shape of the mounting bracket is not a limitation on the present invention. Fender 10 and its components can be shaped to fit the particular mounting bracket in use. For exemplary purposes only, a tubular, u-shaped mounting bracket 34, as shown in FIG. 1, will be described. Others, such as square cross-section or straight mounting brackets, for example, can be employed.

Fender 10 includes top portion 20 and opposed outer and inner walls 24 and 26. At least one element extends from fender 10. Preferably the element is a flange 32. Preferably, flange 32 is outwardly directed. However, in an alternative embodiment, flange 32 can be inwardly directed, as shown in FIG. 7. As used herein, the term “outwardly” means directed away from top portion 20, outer wall 24 or inner wall 26, to which it is attached or from which it projects. The top portion 20, outer wall 24 and inner wall 26 each have a bottom edge 20 a, 24 a and 26 a, respectively. Top portion 20 has opposite ends 20 b and 20 c. In a preferred embodiment, bottom edges 20 a at the respective opposite ends 20 b and 20 c are substantially parallel and are substantially perpendicular to bottom edge 26 a of inner wall 26. Preferably, the flange extends from bottom edge 20 a or 26 a of top portion 20 or inner wall 26. More than one flange 32 can extend from each of bottom edges 20 a, 24 a and 26 a, or one continuous flange 32 can extend around the entire perimeter (comprising bottom edges 20 a, 26 a and 24 a) of fender 10 or any portion thereof, as shown in FIG. 3.

In a preferred embodiment, flange 32 adapts approximately to the contour of mounting bracket 34. However, it is within the scope of the present invention to employ an element, surface or flange that does not adapt to the contour of mounting bracket 34, but only engages mounting bracket 34. Flange 32 defines a longitudinal axis A as shown in FIG. 1. As shown in FIG. 2, if mounting bracket 34 is tubular, flange 32 has an arcuate cross-section transverse to longitudinal axis A. Flange 32 can include at least one hole 36 for securing fender 10 to the mounting bracket 34 using threaded fasteners 38 or the like. After the mounting bracket is secured to the object to which the fender is to be attached the fender is releasably secured to mounting bracket 34 using threaded fasteners.

The elements of fender 10 (top portion 20, outer wall 24, inner wall 26 and flange 32) preferably are comprised of a rigid material, for example, a metal such as stainless steel or aluminum, a plastic, fiberglass, etc. Also, fender 10 can be formed as one continuous piece, or two or more separate elements can be attached to one another by a conventional attachment method such as welding, fastening with bolts or the like.

As shown in FIG. 4, a conventional auto trailer 12 includes a frame 14 having at least one axle 16 with wheels 18 and tires 30 rotatably mounted at opposite ends thereof. Mounting bracket 34 is secured to trailer 12 in a conventional manner, such as by screws, bolts, welding or bonding. Fender 10 is mounted on mounting bracket 34 such that flange 32 is registered or aligned with mounting bracket 34. The conformal shape of the flange(s) 32 enables the operator to determine when fender 10 is in the correct position on mounting bracket 34. The fenders 10 are secured to the mounting brackets 34 and over the tires 30 by slipping threaded fasteners 38 or the like through holes 36 and securing them therein as is conventionally known. Alternatively, fender 10 can be secured to mounting bracket 34 by a conventional method, such as welding, riveting or the like. It should be understood that in a preferred embodiment a right-side fender is a mirror image of a left-side fender. However, this is not a limitation on the present invention.

In an alternative embodiment illustrated in FIG. 5, fender 110 includes a clearance increasing portion 122 between top portion 120 and inner wall 126. The clearance increasing portion 1 22 allows wider objects, such as a car, to fit onto the trailer than would otherwise be possible without it. Fender 110 includes at least one flange 132 extending from at least one of either inner wall 126 or top portion 120. Fender 110 can also include a light housing 60.

Another alternative embodiment according to the invention is illustrated in FIG. 6. Fender 210 is provided for at least partially surrounding two tires 30. Fender 210 includes a top portion 212 that preferably has a substantially flat middle section 214 and curved end sections 216. Alternatively, top portion 212 can include a flat middle section and flat end sections that connect to the middle section at an angle. Fender 210 can also include a clearance increasing portion as described above. Fender 210 includes at least one flange 232 extending therefrom that is adapted to engage a mounting bracket 234.

Another alternative embodiment of a fender 310 according to the present invention is shown in FIG. 8. As illustrated, one or more hooks 332 can be used instead of a flange for engagement with the mounting bracket 34. The hooks 332 can include holes 336 through which a threaded fastener can extend, thereby affixing the fender 310 to the mounting bracket 34. The hooks 332 can extend outwardly, as shown, or inwardly, and can be disposed at various locations on the fender. If desired, a combination of hooks and flanges can be used, for example, with a flange extending along inner wall 26 and hooks at either end of top portion 20.

Another alternative embodiment of a fender 410 is illustrated in FIG. 9. As shown, mounting bracket 34 can be affixed to fender 410 and be adapted to engage an element such as an arcuate flange 432 of the trailer 12. Arcuate flange 432 can include holes 436 for affixing fender 410 to trailer 12. A plurality of hooks can replace arcuate flange 432. Mounting bracket 34 can extend outwardly (as shown) or inwardly.

As described above, when mounting a fender on a trailer, alignment can often be difficult. The present invention provides one or more elements affording instantaneous alignment of the fender. This makes the job of installing a fender on a trailer easier and faster. The advantageous placement of the element or elements also strengthens the fender and protects from fatigue failure due to repeated loading and unloading. The amount of surface area of the element or elements that engages the mounting bracket distributes the weight of a person stepping on the top surface of the fender, thereby preventing concentration of forces at a specific point, as is common with trailer fenders.
